To the Editor: We read with interest the article titled “Cardiovascular Abnormalities in Late Onset Pompe Disease and ERT” by Forsha et al. 1. Ninety patients were randomized 2:1 to enzyme replacement ...

TO THOSE with extensive electrocardiographic experience, especially if it includes a large proportion of young adults, the finding of the pattern of a short PR interval and a prolonged QRS complex ...

The diagnosis is sinus tachycardia, short PR interval (enhanced AV conduction), and Duchenne muscular dystrophy. The rhythm is regular at a rate of 100 beats/min. A P wave occurs before each QRS ...

In myocardial excitation, the delay between the excitation of the atria and ventricles is determined by the sum of atrial and atrioventricular nodal conduction. This delay, measured in milliseconds, ...

A RECENT review of experience with the syndrome of short PR interval and abnormal ventricular complex occurring in otherwise healthy persons prone to paroxysmal tachycardia disclosed that a third of ...

2. Short PR interval and delta waves consistent with Wolff-Parkinson-White (WPW) syndrome Explanation: Wolff-Parkinson-White syndrome occurs when a person is born with an "accessory pathway" that can ...

This ECG shows every other beat having a short PR interval and a delta wave. This is called WPW-alternans. The accessory pathway that is exists is refractory on an alternating basis creating this ...
